I"m setting up a 120g tank and am going to run an automated co2 system, and was what size cylinder would be the best for it.any help would be great, thanks
 
I have a 5 lb for my 75. I've had it going a month and haven't used much. Since your tank is larger, you may want to go with a 10 lb.
 
I'd get as big a tank as will fit in your cabinet and as heavy as you can comfortably move yourself.
